This zip file contains two pdf files - one blank timeline and one filled in timeline. The scientists included are the ones students need to know for Virginia SOLs: Democritus, Dalton, Thompson, Planck, Millikan, Rutherford, Bohr, de Broglie, & Heisenberg. For each scientist there is a spot for students to take notes about his accomplishments and a spot for students to draw that scientist's atomic model if necessary.
I use this timeline as an ongoing tool for students to take notes as we discuss these scientists in class. This is suitable for any first year chemistry course.
